Abstract

ABSTRACT Tunisia is located at a key position in the Mediterranean Sea where it constitutes a transitional area between the eastern and western basins benefitting from rich habitat diversity. The most recent inventory of marine macrophytes dated back to 1987 with an update in 1995, however these inventories were performed with identification based on morphological observations, which can be misleading for many seaweed species. To the best of our knowledge, this is the first study of the Tunisian macroalgal flora using DNA barcoding methods. Our target was to carry out a survey of macroalgae, to reveal cryptic species and allochthonous introductions, and to identify taxa with problematic taxonomy. COI-5P sequence analysis resolved 26 genetic species, including two new reports and three alien species. Of the remaining taxa, several displayed cryptic diversity relative to species reported from the Mediterranean versus from other geographical regions with taxonomic and nomenclature updates provided where possible. The aim of the present paper was to provide a DNA barcode-assisted floristic list of florideophycean algae collected along the Tunisian coast.

DNA条形码揭示了突尼斯红藻区系的新记录

突尼斯位于地中海的关键位置，它构成了东西方盆地之间的过渡区域，受益于丰富的栖息地多样性。最近的海洋大型植物清查可追溯到1987年，并于1995年进行了一次更新，但这些清查是基于形态学观察进行的鉴定，这可能对许多海藻物种产生误导。据我们所知，这是第一次使用DNA条形码方法对突尼斯大藻群进行研究。我们的目标是开展大型藻类的调查，揭示隐种和外来引种，并查明分类上存在问题的分类群。COI-5P序列分析确定了26个遗传种，包括2个新报道种和3个外来种。在剩余的分类群中，有几个分类群与地中海和其他地理区域报告的物种相比表现出隐晦的多样性，并尽可能提供了分类和命名法的更新。本论文的目的是提供一个DNA条形码辅助的植物区系清单，收集沿突尼斯海岸的藻类。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
